We have finished production and began shipping EGR block off plates for the 6.7 engines. Installation is very simple, bolt on install using all factory hardware. No drilling or modifications needed, and work should take less than 30 minutes to complete. These plates allow you to install a EGT probe 1/8 NPT into the exhaust manifold without drilling.

What about drive pressures? Do these things wastegate through the EGR like the 6.4? Just wondering if any damage could occur?

That would be a question for H+S as the EGR function is turned off in the tuning already, so the plates don't affect that at all. These power levels are fairly low right now so I wouldn't think it would be an issue. The plate on the manifold sure gives us a great location to test drive pressure if it was a concern. If these 6.7 prove to be as durable as the 6.4's, drive pressure only really became an issue as the tuning/hp increased in 275 hp + tunes.

He is correct. Drive pressure is not much of an issue yet, and I doubt it will be for quite some time. We will try to incorporate a few new PIDs to monitor, including drive pressure, on the BM and MM units. This may be some time down the road, but is for sure on our list of things to get tackled.

It is more of a EGT probe mounting solution as of now, but does remove any possiblity of a failed EGR cooler filling the engine with coolant. It reads PRE turbo EGT in the right side exhaust manifold by hanging the EGT probe into the manifold just forward of centered. It will also reduce the EGR/ intake charger cooler water temps by keep exhaust away from the EGR coolers. This will reduce intake charge temps by not using exhaust to heat the water. These 6.7 trucks have 2 cooling systems function under the hood. One cools the engine as a traditional system and the second cools intake air side of the engine which includes the water to air intercooler and the EGR system. As far as setting codes, yes a stock truck or even truck programmed which the EGR still function will set codes and cause problems.
